Study Notes
- Plant parts each have multiple functions.
- Organs are made from different types of tissue.
- Cells are the building blocks of plants.
- Cells divide and specialize to form tissue.
- Tissues combine to create roots, stems, buds, leaves, flowers, fruits, and seeds.
Plant Tissues
- Meristematic and permanent tissues are the main types of plant tissues.
- Meristematic tissue consists of identical cells that actively divide to generate new cells.
- Meristematic cells undergo differentiation, developing into cells that differ from one another and from meristematic cells.
- These differentiated cells combine to form tissues and organs.
- Apical meristems are located at the tips of shoots and roots.
- Apical meristems elongate stems and roots through cell division.
- Lateral meristems cause secondary growth, thickening stems and roots for increased stability and support.
- Intercalary meristem exists in grasses at the base of each leaf.
- Intercalary meristem regenerates leafy growth when grass is mowed or grazed.
- Permanent tissue is fully differentiated meristematic tissue.
- Simple tissue consists of only one cell type while complex tissue consists of multiple cell types.
- The epidermis is an example of simple tissue.
- Xylem and pholem are examples of complex tissues.
